Problems solved by technology

The traditional decoction extraction process is: after the Chinese medicinal materials are picked, they are washed, dried, sliced, and then boiled with water, which takes a long time and produces a large amount of waste residue. The waste residue of medicinal materials needs to be landfilled, which is not conducive to environmental protection
[0004] With the penetration of modern medicine in the field of traditional Chinese medicine and the success of artemisinin, people have realized that the traditional decoction method, solvent ultrasonic extraction, etc. may not be the best solution, because during the decoction process, many For components such as volatile oil, many unstable structures are also destroyed during the decoction process at 60°C to 100°C, and ultrasonic extraction requires a solvent
In the prior art, chemical methods are also used to extract the active ingredients of traditional Chinese medicine, but there are disadvantages such as unfavorable to environmental protection, high energy consumption, long process flow, time-consuming labor, and high industrialization cost.
[0005] In order to solve the defects of high-temperature cooking and extraction, a normal-temperature extraction process has also appeared, but the existing normal-temperature extraction process does not have a high-temperature cooking process, so that bacteria cannot be killed, and there are potential safety hazards; and the existing normal-temperature extraction process has no active substances Small, difficult to be extracted in water, usually need to use organic solvent to extract, add catalyst, modifier, etc. high production cost

Embodiment 1

[0023] The device used is an infrared plasma surface modification device, which includes a vacuum pumping device and a sealed casing, and an ultrasonic tank, an infrared emitting device and a plasma generating device are arranged in the casing, and the infrared emitting device and the plasma generating device The devices are all set above the ultrasonic tank.

[0024] The preparation method of dendrobium extract is as follows:

[0025] (1) Crushing: Dry 1Kg of fresh dendrobium at 70°C for 4 hours and put it into a clean high-speed pulverizer (equipment manufacturer: Jiangsu Dongsheng Machinery Co., Ltd., model is FS300, the same below), after starting, pulverize Take it out after 20 seconds, add it to the ultrasonic tank body of the above-mentioned infrared plasma surface modification device, put 5Kg of pure water in the tank, and add the nano-scale particles of Dendrobium candidum polysaccharide simultaneously, the addition of the nano-scale particles of the Dendrobium candid...

Embodiment 2

[0036] Methods as below:

[0037] (1) Crushing: Dry 1Kg of fresh dendrobium at 70°C for 4 hours and put it into a clean high-speed pulverizer. After starting, take it out after pulverizing for 20 seconds, add it to the infrared plasma surface modification device, and put pure Water 5Kg, add the nanoscale particle of Dendrobium officinale polysaccharide simultaneously, particle diameter is 20nm, the addition of the nanoscale particle of described Dendrobium candidum polysaccharide is 4ppm, temperature adopts normal temperature, vacuum degree 20mmHg, start activation, after 3.5 hours, use filter Filter through a net to obtain the dendrobium extract. After testing, in the dendrobium extract, the polysaccharide of Dendrobium candidum is detected, and in the extract of dendrobium, the polysaccharide of Dendrobium candidum is 27% (that is: the quality of the polysaccharide of Dendrobium candidum is 27% of the input amount of fresh dendrobium) .

[0038] (2) Waste residue: After fil...

Embodiment 3

[0041] Methods as below:

[0042] (1) Grinding: Dry 1Kg of fresh dendrobium at 70°C for 4 hours and put it into a clean high-speed grinder (equipment manufacturer: Jiangsu Dongsheng Machinery Co., Ltd., model is FS300). After starting, grind for 20 seconds Take it out, add it to an infrared plasma surface modification device, put 11Kg of pure water into the instrument, and add nanoscale particles of Dendrobium officinale polysaccharide at the same time, the addition amount of the nanoscale particles of Dendrobium officinale polysaccharide is 5ppm, and the particle size is 50nm. Temperature adopts normal temperature, vacuum degree 20mmHg, start activation, after 4 hours, filter with filter screen, obtain the dendrobium extract, after testing, in the dendrobium extract, the polysaccharide of dendrobium candidum is mixed with anhydrous glucose (C 6 h 12 o 6 ) is counted as 30%.

[0043] (2) Waste residue: The waste residue obtained by filtering in step (1) is dried at 70°C for...

Description

technical field [0001] The invention belongs to the technical field of extraction of effective components of Chinese medicinal materials, and in particular relates to a preparation method of a dendrobium extract at normal temperature. Background technique [0002] Traditional Chinese medicine mainly originated in China, and is a drug used to prevent, diagnose, treat diseases or regulate human body functions under the guidance of TCM theory. Most of them are herbal medicines, but there are also animal medicines, mineral medicines and some chemical and biological products. Traditional Chinese medicine is divided into Chinese patent medicine and traditional Chinese medicinal materials according to the processing technology. For Chinese herbal medicines, how to efficiently extract their active ingredients is one of the current research hotspots. [0003] For a long time, clinical Chinese herbal medicines have been mainly decocted in water. The traditional decoction extraction...
